Application led 4January S. 1907. Serial No. 350.564.

To all whom it may concern:

Be it known that I, HENRY JOHN Ross, a subj ect of the King of Great Britain, resident of No. 71 Queen street, in the city of St.

Catherines, county of Lincoln, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

My invention relates to improvements in calks for horse-shoes, and the object of the invention is to devise a calk, which shall be readily removable from the horse-shoe, thereby providing a calk always ready for use and easily attached to the shoe at a moments notice, when the state of the road makes it a necessity to prevent the horse from sliding, and whereby the constant sharpening of permanent calks on a shoe is entirely obviated, and it consists essentially of segmental sections of metal together forming a horse-shoe shape and having pointed tread portions at the front and rear thereof, and means for fastening said segmental sec tions to the shoe, the various parts being explained in detail in the following specification and shown in the drawings that form part of the same.

In the drawings, Figure 1 is a perspective view of a horse-shoe reversed with my invention applied thereto and the points of the calks projecting upwardly. Fig. 2 is a perspective view of the calks apart from the s oe. Fig. 3 is a transverse section centrally through the calks and shoe.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 2 is the horseshoe, here shown as formed with an ordinary permanent front calk 3 and the two permanent rear calks 4.

5 are lengths of metal of segmental formation and forming sections of the removable calk and having at the front ends thereof the tread points 6 and at the rear ends the tread points 7, and corresponding to the shape of the horse-shoe, when the front tread points 6 are drawn together and the rear tread points 7 placed apart. The front tread points 6 have fiat outer faces and in position on the shoe abut the front calk 3, projecting downwardly therebeyond in order to make the first grip on an icy road or other slippery surface. The rear tread points 7 abut the inner surfaces of the rear calks 4 and project downwardly therebeyond for the same reason.

8 are lugs projecting laterally and' inwardly from the segmental sections 5 mid-way of the length of said sections and having the dove-tailed slots 9 therein vertically arranged at the inward extremities thereof.

10 are grooves in the inner and upper surfaces of the sections 5 leading from the slots 9 and extending in a flaring direction to the outer edges of the said sections 5. 11 are nuts correspondingly dove-tailed to said dove-tailed slots 9 and fitting loosely therein.

12 is a squared bolt having the reduced threaded ends 13 and 14 with right and left threads respectively turning in the nuts 11 and drawing said nuts and consequently the sections 5 together or setting said sections further apart according to the direction in which the said bolt is turned. The threaded ends 13 and 14 extendinto the grooves 10, and as the said grooves are cut in a flaring manner and the nuts 11 fit loosely in the slots 9 the segmental sections 5 are free to swing laterally and may be drawn in or set apart so as to fit almost any horse-shoe.

15 is a lock-nut of any suitable pattern on the end 13 of the bolt 12 to prevent said bolt from turning when it is desired to retain the sections 5 in position on the shoe.

It may be here explained that the lugs 8, as well as projecting inwardly from the sections 5 as described, also project u wardly therefrom to approximately the thiol) a horse shoe and have the lips or ears 16 projecting therefrom to catch the-up er inner edge of the shoe, so that on turning the bolt to set said sections 5 further apart, the ears16 are forced into position above the horse shoe and the removable calk thus locked securely into position on the shoe. In removing the calks on turning the bolt 12 to draw the sections together, the calk drops off as the ears are taken from engagement, thus making it possible even during a journey to attach or remove the calks according to the state of the road over which the horse may be traveling, and also in case of sudden and violent sleet storms and subsequent freezing having calks always in readiness to apply to the shoes of the horse. Further these calks may be repaired and sharpened without the necessity of taking the horse to a blacksmith and will be found to fully meet and perform the same service as a permanent (ness of call; and a great saving of time and expense will thus be effected.

Vhat'I claim as my invention is:

l. Ahorse-shoe calli, comprising segmental lengths of metal having Jfront and rear tread points land lugs projecting inwardly therefrom about midway of their length, said lugs each having a dove-tailed slot therein and ears from the upper edges for engaging the horse-shoe, nuts correspondingly dove-tailed loosely inserted in said slots, and a bolt having right and left hand threads turning in said nuts, substantially as described.

2. In a calli for horse-shoes, the combination with a horse-shoe having front and rear permanent calks, of segmental sections having front and rear tread points abutting said front and rear permanent calks respectively and inwardly projecting lugs about mid-way of the length of saidsections, said lugs having dove-tailed slots at their inward extremities and upward extensions and ears from said upward extensions for engaging said horse-shoe, nuts correspondingly dove-tailed to said slots and loosely litting therein, and a bolt having right and left hand screws and turning in said nuts, substantially as described.

3. In a calli for horse-shoes, the combinations about mid-way of the length thereof' having ears from the upper projections engaging the horse-shoe and vertically arranged opposing dove-tailed slots at their inward extremities and grooves leading in a Haring direction across the upper side of said sections from the said dove-tailed slots, nuts correspondingly dove-tailed and loosely fitting in vsaid slots, and a squared bolt having reduced ends threaded right andleft respectively and turning in said nuts and adapted to be locked, substantially as described.

Signed at the city of St. Catherines, in the county of Lincoln, Province of Ontario, in the Dominion of Canada, this 6th day of December, 1906.

HENRY JOHN ROSS.
